Safety Precautions

Before using this product, the user is requested to read the following precautions carefully to ensure the

safety.Safety precautions must be taken by every user to prevent accidents.

The safety requirements are classified into “warning” and “caution” according to the following interpreta-

tions:

Warning Suggesting that the user's mishandling can

result in personal death or serious injury.

Caution

Suggesting that the user's mishandling can result

in personal injury or damage to the property.

“Any control system design should take into account that any part of the system has the potential to fail”.

“The most dangerous condition of the system equipped with this product is continued heating, and the ma-

chine should be designed to automatically stop heating even if alarm is not issued at the time of failure of this

product or due to any other reason”.

The following are the most common cases where continued heating cannot be detected with this product.

1) Failure to issuing an alarm even when this product fails

2) Disengagement of the temperature sensor from the system

3) A short circuit in the thermocouple wiring

In any application where physical injury or destruction of equipment might occur, we recommend the instal-

lation of independent safety equipment, with a separate temperature sensor, to disable the heating circuit in

case of overheating.

Digital thermostat alarm signal is not designed to function as a protective measure in case of product failure.

1. Warning

1.1 Installation and wiring

•This product designed to be installed at the conditions shown in the right table.

•If there is a danger of a serious accident resulting from a failure or a defect in this unit, provide the unit

with an appropriate external protective circuit to prevent an accident.

•The unit is supplied without a power switch and fuses.

Make wiring so that the fuse is placed between the main power supply switch and this product.(Main

power supply: 2 pole breaker, fuse rating: 250V, 1A)

•When wiring the power supply terminal, use vinyl insulated 600 volt cable or equivalent.

•To avoid the damage and failure of this product, supply the power voltage fitting to the rating.

•To avoid an electric shock and this product failure, do not turn ON the power before all wiring is

completed.

•Be sure to check that the distance is kept to avoid electric shock or firing before turning the power ON.

•Keep away from terminals while the circuit is energized in order to avoid an electric shock and a

malfunction.

•Never attempt to disassemble, fabricate, modify, or repair this unit because tampering with the unit

may result in a malfunction, electric shock, or a fire.

1.2 Maintenance precautions

•Be sure to turn off the power before this product is installed or removed in order to avoid an electric

shock, malfunction, and fault.

•Regular maintenance is recommended a longer service life of this controller. Some parts of this con-

troller have a limited life span, or they will be deteriorated with the lapse of time.

•One-year warranty is guaranteed for this unit including accessories, provided that the controller is

properly used.

(Caution)

•Don’t block the openings around this product, or radiation effect will be reduced.

•Don’t block the ventilation openings at the top of the terminal block.

2. Caution

2.1 Cautions on installation

Avoid the following places for installation.

•A place where the ambient temperature may reach beyond the range of from 0 to 50°C while in

operation.

•A place where the ambient humidity may reach beyond the range of from 45 to 85% RH while in

operation.

•A place where a change in the ambient temperature is so rapid as to cause condensation.

•A place where corrosive gases (sulfide gas and ammonia gas, in particular) or combustible gases are

emitted.

•A place where the unit is subject directly to vibration or shock. (vibration or shock may cause malfunc-

tion of the output relay.)

•A place exposed to water oil, chemicals,steam and vapor.

(if immersed with water, take the inspection by sales office to avoid an electrical leakage and firing )

•A place where the unit is exposed to dust, salt air, or air containing iron particles.

•A place where the unit is subject to intereference with static electricity, magnetism, and noise.

•A place where the unit is exposed to direct sunlight.

•A place where the heat may be accumulated due to the radiation of heat.

2.2 Cautions on installation on panel

•Insert the mounting bracket (accessory) from the rear side until the main unit is securely fit into the

panel. If there should be a play, tighten two screws lightly until the play is eliminated. (Do not tighten

the screws excessively because the mounting bracket can be removed from the stopper by the force.)

•The front side of product to NEMA 4X(equivalent with IP66).To ensure the waterproofness between

the instrument and the panel, use packings that are provided as accessories in the following manner:

(The improper fitting of packings will ruin the waterproofness.)

qAs shown in Figure 1, fit a packing to the case of the unit and then insert it in the panel.

wTighten screws on the fixing frame or fixtures so that no gaps are given between the front of

controller and packing and between panels.

Check that there are no deviation and deformation of packing as shown in Fig.3.

•If panel strength is weak, it may generate a gap between the packing and the panel, thus impairing

water resistance.

2.3 Precautions in wiring connection

•For the thermocouple sensor type, use thermocouple compensation wires for wiring.

•Keep input lines away from power line and load line to avoid the influence from noise induced.

•For the input and output signal lines, be sure to use shielded wires and keep them away from each

other.

•If a noise level is excessive in the power supply, the additional installation of an insulating transformer

and the use of a noise filter are recommended.(example:ZMB22R5-11 Noise Filter manufactured by

TDK)

Make sure that the noise filter is installed to a place such as a panel that is properly grounded.The

wiring between the noise filter output terminal and the instrument power supply terminal should be

made as short as possible. None of fuses or switches should be installed to the wiring on the noise

filter output side because the filter effect will be degraded by such a installation.

•A better anti-noise effect can be expected by using stranded power supply cable for the instrument.

(The shorter the stranding pitch is, the better the anti-noise effect can be expected.)

•A setup time is required for the alarm output when the power is turned on. If the alarm output is used

as a signal for an external interlock circuit, use a delay relay at the same time.

•Use the auxiliary relay since the life is shortened if full capacity load is connected to the alarm output

relay.

•If inductive load such as magnetic switches connected as a alarm output load, it is recommended to

use Z-Trap manufactured by Fuji Electric to protect a contact from switching serge and keep a longer

life.Model : ENC241D-05A (power supply voltage: 100 V)

ENC471D-05A (power supply voltage: 200 V)

Where to install : Connect it between contacts of the alarm output.

Example)

2.4 Requirement for key operation/operation in abnormalities

•A display of UUU or LLL will appear in case of a break in the input. Be sure to turn off the power when

a sensor is replaced.

•Do not turn OFF the power for at least five (5) seconds if the alarm set value or any parameter was

changed.

2.5 Others

•Do not use organic solvents such as alcohol and benzine to wipe this controller.Use a neutral deter-

gent for wiping this product.

•Do not bring any mobile phone close to the main unit (50 cm). Malfunction will occur.

•Noise may be produced if this equipment is brought close to a radio. Use this equipment as fully

spaced apart from radios.

•Do not push the display unit (LCD) on the front face of this equipment with force. Observation of the

display (LCD) will become hard.

•This equipment issues an LCD as the front display. There are cases where the display can be hardly

observed at a slant because of the characteristics of LCD.

•Observation of the display (LCD) will become hard when the ambient temperature drops to a level

close to 0°C.
